To all whom z'tmay concern.'

Beit known that I,.,PHILIIl MUELLER, a' citizen of the United States,iesiding at Decatur, in the county of Macon andState-ot' l Illinois,have inventednew and usefulImv removed and which' is adapted for eitherhigh -oi low pressure service.

In vorder that'the invention may be clear Vto those skilled inthe art, Ihave illustrated, inthe drawings herewith, embodiments of my invention,which embodiments, rmay, however, be varied from the mechanical'adaptations shown without departing Yfrom the invention, the disclosurebeing illustrative, merely, and not restrictive.

" In said drawings:

:parts Ybeing in section for clearness ofillus- Y Y tration,` of a valveconstructed in accordance with my invention. y l

Fig. 2 is a top plan,.partly in section, of the valve shown yinFig. 1.Fig.v3 shows a 'slightly different arrange nient of the valve parts. 1

Fig. 4 is a sectional viewof the form of valve-shown in Fig'. 3.

Having reference to the drawings by numbers, .like numbers designatinglike parts in the several views, 10 indicates the inlet stub, provided,as is customary, with nutsV 11 and tank (not shown) and to the supplypipe (not shown).

The stub 10, in the form of the invention shown in Figs. 1 and 2, isconnected by an elbow-passage 13 with thecasingl ofthe out.` let Vvalve14, which, in turn, is controlled by the float-.lever 15, to which anysuitable iioat (not shown) may beiattache v The stub 10 has `a throughpassage, as

shown, said passage being straight and of diierent diameters. In thesmall section bore of the stub, as shown in Figs.' 1 and 2, is locatedthe flo-w-impeding member or silencer, comprising the central rod 17hav- 'Y ing the spiralv rib` 18, which engages fric- 'Fig l is a view inside elevation, certainr 12 for securing it to the usual receptacle or iis inv place a tortuous passage is provided,

I. Theadvantage of' this construction is, that time removed,withoutdisturbing .the fitting,

.by simply removing the cap-nut 16, and any` the valve is adaptedftoeitherhigh or low pressure service. If the pressure vis low, the`silenoer'may'be initially omitted, or at 'any clogging of the valve byreason ofsediinent or foreignf-matters collecting therein,:may:v f

be readily taken-'care of'. If the pressure bef 1 high, thev silencermay be initially installed i or at any time supplied to thefittingwithout the necessity of changing the-equipment y l .f Y. 'or taking itdown `for refassembling to con- 1 form to and .meet the needs of highpressure.- InV that form of 'the invention shown' kin IFigs.3 and 4, Ivhave disposed thesilencer in a slightly ldiiIerent manner, having'arranged cross-passage y19 `being somewhat. elongated and closed at itsouter end by a nut 20, which' Vmay be -readily removedvwithoutdisturbing the rest of .theiitting, so as to permitthe silencerto be withdrawn or inserted,l as mayl be desired.

The stub 10 has, in both fornisy disclosed,`

the l'chambered section 21 fitted to its top with a watertightfjoint andheld securely by the cap-nut16,.as shown in vFigures 1 and 2`1and vbythe clamping nut 24, as sho-wn in Figures 3 land 4, and 'additionallyiiithe passesthru a suitable stuiing box 23, `avwing parts .iny position.

ioni term shown in Figs. 3y and 4 there `is proi VVvided a regulationand stop valve 22' Which;

In float valves of this type it customary f to provide bumpers andLthelike o-n the lioator float lever to limitthe downward m0ve.y l

11o f I and dan'iaged; and, furthermore, Where the float` does notifa-ll to the bottom, to relieve the valve ot the strain and jammingaction incident to sustaining the Weight of the float and float lever,l' accomplish these results Without the necessity of cumbering theequipment with bumpers, by putting .a stop 25 on 1the casing in positionto be engaged by the toe 9A projecting Yfrom the float lever 15 so as tolimit the fall orI the opposite end of the 'float lever and the float(not shown) dthereby, and prevents bumping of the i oat.

The float lever l5 is angularly adjustable on theserrated end 2G oi thisvalve stem 27,

`and is locked thereon by set screw 28, so that it may be adjusted togive ythe requisite travel ot thel valve stem to ensure pro er openingand closing ol the valve. By tiis arrangement of adjustable Vfloat leverand lever stop, l am enabled to initially install the valve so as to geta proper opening and vanl accurate seating of the valve, and toconveniently compensate for valve Wear after use, Without the'necessityotbumpers or stops on the iloau or float levers.y l

rll'he constructions-:ds such that both installation or change, vt'orhigh and low vgressures, is readily. accomplished, and While l am aivarethat silencers have been used in e uiipments oi this general type, theyhave, as known to me, been so arranged that they vvere not readilyaccessible 'tor removing or inserting them tor dill'erent pressures orfor cleaning.
